Scarlett Johansson is a first time mother!
The actress behind Black Widow and Lucy welcomed a baby girl with the great name of Rose today, as fiance Romain Dauriac was by her side for the delivery.
Johansson's rep confirmed this exciting news to The Associated Press, who reports that "mother and daughter are doing well."
The 29-year old kept a very low profile while pregnant, rarely making public appearances.
She was married to Ryan Reynolds for two years until the couple divorced in 2010 and both moved on (he's now hitched to Blake Lively.), with Johansson getting engaged again about a year ago.
We send our very, very best wishes to the newly expanded family!
